Quick Start

This guide helps you integrate with the HaoAI Gateway and start calling 100+ LLMs in just 3 minutes.

Prerequisites

Sign up at the HaoAI Console and get an API Key
Have a development environment ready (Python 3.8+ / Node.js 18+)

HaoAI is compatible with all three major protocols — OpenAI / Anthropic / Gemini. You can use any official SDK to connect.

Choose Your Protocol

OpenAI SDK (Recommended)

OpenAI Compatible Protocol — The most universal integration method.
